Abstract

Calculations are performed for electron collision with the methylene molecular ion CH2+_2^+ in its bent equilibrium geometry, with the goal to obtain cross sections for electron impact excitation and dissociation. The polyatomic version of the UK molecular R-matrix codes was used to perform an initial configuration-interaction calculation on the doublet and quartet states of the CH2+_2^+ ion. Subsequently, scattering calculations are performed to obtain electron impact electronic excitation and dissociation cross sections and, additionally, the bound states of the CH2_2 molecule and Feshbach resonances in the ee-CH2+_2^+ system.
